Aqueminianswered grow question 3 years ago I run 1 tent that stay on 24 hours a day. I put Autoflowers and Photoperiods in there. I move my photoperiods to a dark room when I want to flower them. I run all my plants under 24 hours vegetation light.
You can run any setup you want. You just have to learn what works for you. If your running all Autoflowers then all of them can go in the same tent regardless the light schedule.
If you run photoperiods you'll need a dark room or to run your whole tent 12/12.
I'm practicing a perpetual grow with 1 tent, and 1 dark room.
